menu "I2O device support" config I2O tristate "I2O support" depends on PCI ---help--- The Intelligent Input/Output (I2O) architecture allows hardware drivers to be split into two parts: an operating system specific module called the OSM and an hardware specific module called the HDM. The OSM can talk to a whole range of HDM's, and ideally the HDM's are not OS dependent. This allows for the same HDM driver to be used under different operating systems if the relevant OSM is in place. In order for this to work, you need to have an I2O interface adapter card in your computer. This card contains a special I/O processor (IOP), thus allowing high speeds since the CPU does not have to deal with I/O. If you say Y here, you will get a choice of interface adapter drivers and OSM's with the following questions. To compile this support as a module, choose M here: the modules will be called i2o_core. If unsure, say N. config I2O_CONFIG tristate "I2O Configuration support" depends on PCI && I2O help Say Y for support of the configuration interface for the I2O adapters. If you have a RAID controller from Adaptec and you want to use the raidutils to manage your RAID array, you have to say Y here. To compile this support as a module, choose M here: the module will be called i2o_config. config I2O_BLOCK tristate "I2O Block OSM" depends on I2O help Include support for the I2O Block OSM. The Block OSM presents disk and other structured block devices to the operating system. If you are using an RAID controller, you could access the array only by the Block OSM driver. But it is possible to access the single disks by the SCSI OSM driver, for example to monitor the disks. To compile this support as a module, choose M here: the module will be called i2o_block. config I2O_SCSI tristate "I2O SCSI OSM" depends on I2O && SCSI help Allows direct SCSI access to SCSI devices on a SCSI or FibreChannel I2O controller. You can use both the SCSI and Block OSM together if you wish. To access a RAID array, you must use the Block OSM driver. But you could use the SCSI OSM driver to monitor the single disks. To compile this support as a module, choose M here: the module will be called i2o_scsi. config I2O_PROC tristate "I2O /proc support" depends on I2O help If you say Y here and to "/proc file system support", you will be able to read I2O related information from the virtual directory /proc/i2o. To compile this support as a module, choose M here: the module will be called i2o_proc. endmenu
